To all whom it may concern:

Be it known that I, CHARLES A. KEEDWELL, a subject of the King of England, and a resident of New York, borou h of Bronx, in the county of Bronx and mm of New York, have invented a certain new and useful Composition of Matter for Coating Surfaces, of which the following is a full, clear, and exact specification.

This invention relates more particularly to a class of paints.

My invention has for its object primarily to provide a com osition for coating surfaces designed to l fe employed especially as a graining paint for decorating and finishing buildings, furniture, automobiles, railway cars and elsewhere so that the exposed surfaces thereof may be made very attractive in appearance by being colored with a layer in a manner representing various classes of mottled and variegated color effects, such as the representation of different Woods and the like. The invention contemplates the provision of a coating which includes mainly sodium silicate an astmgent thinning liqui a viscous material and a fifimoportions so that the coating wi of a consistency and viscosity whereby it may be spread by a brush or pad on a surface in one or more thin or thick layers without tendency to flow or run as well as being of a consistency so that it may be spread whereby parts will be of greater density than other parts, in order to provide various novel and attractive effects. The coating when colored, which may be applied in one or a combination of tints, is usually of a. color contrasting with the color of the surface. When desired a primary base layer or foundation of a suitable color may be provided on the surface prior to the application of my improved coating.

In practicing the invention the surface to be decorated or finished, whether a part of a building, or furniture, or a vehicle, such as an automobile, railway car and the like, may be painted with a primary foundation or coat of a suitable color if such a foundation coat is absent from the surface, or the coating may be applied on a painted surface wlfiiflh is desired to be redecorated or refin- 1s e Application fledm1922. Serial No. 565,485.

composition includes an astringent thinning liqul suc as an aqueous solution of a viscous material, such as lucose r s vofs a or other saccharin sn 5 ance to impafi to The coating an a esive o y. To these ingredients is added a imnent of a suitable lor and I may also add thereto a volatile l quid, such as alcohol. The formula 0 t e composition w 10 prefer to use consists of twenty P cent of sixty P cent of a solution of alum of a three per cent strength, eighteen per cent of sugar syrup and two per cent of alcohol.

These ingredients when thoroughly mingled together by the employment of appropriate means provide a vehicle which when spread on a surface will firmly adhere there to without tending to flow or run, and which will dry quickly as well as holding a pigment in proper suspension. The pigment when mixed in this vehicle may be of any selected color, and any suitable quantity of the pigment may be used to render pro er consistency to the coating so that by wiping or rubbing the layer or layers of the coating following its application to the surface parts of the coating will be in thin layers, and other parts will be in dense layers to produce very attractive mottled and variegated effects, especially when the coating is of a color contrasting with the color of the foundation coat. Also by skillfully manipulating the coating when spread on the surface grain effects representing various hardwoods may be obtained.

It will be understood that I do not limit myself to the precise components of the foregoing formula, but may use modifications, or equivalents thereof, such as fall within the scope of the appended claim.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
